MoroR-rRorELLEn VEHICLE.

To all whom it may concern o Be it known that 1, WILLIAM SCHIERDING, a subject'of the Emperor of Germany, residing at'Wallace, in the county of Shoshone and State of Idaho, have inventedcertain new and useful Improvements in -Motor Propelled Vehicles, of which the following is a specification. V o 7 V Y The invention relates to improvements in motor'propelled vehicles.

The object of the present invention is to improve the construction of motor propelled vehicles, more especially the construction of the propelling mechanism and to provide simple, efficient and comparatively inexpen:

. sive propelling mechanism of strong and I pushing or propelling bars being injured durable construction adapted to be readily applied to various kinds of vehicles, whether.

wheeled or sleighs, and capable of yield.- ingly engaging a roadway or other surface at a plurality of points, and of rapidly propelling a vehicle Without liability of its through contact withinequalities of rough surfaces.

A further object of the invention is to provide adjustable propelling mechanism capable of being readily raised. and lowered to arrange it. clear of the ground and also to position itproperly to suit the height of the vehicle and the character of the surface over which the same may be traveling so. as'to secure a. proper engagement therewith.

With these and other objects in view, the invention consists in the construction .and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size, and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, only the running gear 1 of a wheeled vehicle is illustrated, as the invention is applicable to all kinds of vehicles and the particular'construction of the body of the vehicle .does not constitute a portion of the present invention and maybe varied in con-- structi'on. as desired. The running gear 1 includes a front aXle 2 pivotally connected with and supporting a front'bolster 3 to which is secured the front ends of the side 1 bars The side bars 4 extend rearwardly to and are supported by a rear axle 5 to which they are secured; and the said side bars are connected by intermediate cross bar 6 and constitute the supporting frame work of the running gear, but the latter may of course be varied to suit the character of the.

vehicle to which the propelling'mechanism is applied. The front'aXle carries a toothed segment 7 preferably secured to the upper face of the aXle and'eXtending rearwardlytherefrom and meshing with a'toothed segment 8 mounted on a central pivot 9 and connected at opposite sides with the terminals of a cable10or'othersuitable flexible connection. The pivot'9 issuitably mounted on the running gear at the intermediate mounted in suitable bearings of spaced supv porting arms between which the drum 12 '7 of the drawings.

is arranged. The steering wheel is adapted to be turned similarly to the steering wheel of an automobile for oscillating the pivotally mounted segment to turn the front axle on its axis for steering the latter, and while the shaft of the steering Wheel is shown in a vertical position, it maybe arrangedin any other suitable manner.

The vertical shaft 13 is located at one side of the median plane of the vehicle and one of the side branches or portions of the cable 10 extends directly from the drum to the pivoted segment, and the other side portion or branch of the cable passes around a centrally arranged guide pulley 16 and extends therefrom to the opposite side of the pivoted segment. Theguide pulley is located back of the vertical shaft and is laterally offset from the longitudinal plane of the same a suilicient distance to afford an easy pull on the side of the pivoted segment to which the adjacent guided portion of the cable is connected. The guide pulley is mounted in a suitable bracket orsupport 17. whichis suitably mounted on the rear axle. Any other suitable means may be employed for properly guiding the cable or other flexible. connection of the steering mechanism. Thesegmentsare preferably open and consist of curved peripheral portions and straightdiametrically arranged connectingportions. The peripheralportions are located beneath forwardly converging reach bars or braces 18, and are guided between the same, and a bottom brace 19 having for- .wardly diverging sides arranged in spaced relation with the reach bars and having upwardly bent front terminals secured to the same at the opening of the segment of the front axle, as clearly illustrated in Fig. 3 The rear end of the brace 19 extends to and is pierced by the pivot 9 of the segment 8. The forwardly converging reach bars or braces 18 are secured at their rear portions to the rear axle and they are preferably provided with an integral connecting front portion 20 through which the king bolt- 21 of the front axle passes. No claim is made in the present application to the steering mechanism.

The reach bars or braces are extended be yond the rear axle to form supporting arms 22 bifurcated at their rear terminals 28 to receive side links or bars 24 and 25 of a pivotally mounted support, and having bearings at oppositesides of the bifurcations for the reception of terminal journals or g'udgeons of a front crank shaft 27. The front crank shaft is journaled at its center in suitable. bearings of an arm 28 extending rearwardly from the'rear axle and prefer-- ablyv constituting a portion of the bracket or support 17 in which the guide pulley 16 is mounted, but the supporting arm may be constructed in any other suitable manner.

The central-rearwardly extending supporting arm is provided with a slot or bifurcation 29 for the reception of a sprocket wheel 30' suitablyfixed to'the front crank shaft at the centerthereof and connected with a gasolene engine 31 or other motor.

shown in the accompanying drawings, the sprocket wheel 30 is connected bya sprocket chain'32 with a sprocket-pinion 33 of an intermediate transversely disposed counter-- shaft 84 journaled in suitable bearings at the rear axle, and carries a pulley 351 which is connected by a belt 36 with a driving pulley 37 on the engine shaft 38, but any other suitable means may beemployed for transmitting motion from the engine or motor 31 to the intermediate transverse shaft 34.

The front crank shaft 27 constitutes a 7 member 44 is provided at the top with spaced eyes 45, receiving a transverse pivot 46 which 1s supported in a superimposed position with relation to, the inner ends of the central'an'd side links 42 and 25 by the side links 24 pivotallv mounted on the terminal journals or gudgeons of the front crank shaft 27, as clearly illustrated in Fig. 2 of the drawings. The front crank shaft is provided with crank bends 47 corresponding in" number and in position with thec'rank bends 40 of the rear crank shaft and connected therewith by parallel links or bars 48 which cause the front and rear crank shafts to move in unison. The crank bends" extend radially from the axis of the crank shafts at differentpoints around the same and any desired number of crank bends and propellers or push bars may be employed, four sets of such devices being illustrated in the accompanying drawings. The propeller or push bars are arranged in a'perpendicular position 'when the rearwardly extending links or bars 25 and 42' are in a horizontal position, and'they are maintained in such relative position by inclinedbraces or thrust bars 49 having bifurcated terminals to receive the front ends of the parallel links 4' and the lower portions of the push bars. Each inclined brace or thrust bar'or mem ber is provided at its upper or front end with hearings to receive the contiguous crank bend of the front crank shaft, and its lower or 'rear end is connected with the lower portion of the contiguous push bar by a transverse pivot 50.

The crank shafts are adapted to be rotated in-either direction for propelling the vehicleforwardly or backwardly, and when.

the crank shafts are rotatedin a forward other supporting;- surface when the crank bends swing downwardly'and they are moved rearwardly with respect to the vehicle bythe backward movement of the crank bends, and they are lifted by the upward movement of the crank bends at the end of each actuating stroke and are carried forward in an elevated position and again engaged with thesupporting surface, the operation being repeated during the rotation of the crank shafts and the push bars successively engaging with the ground or other supporting surface through the opposite arrangement of the crank bends. By this construction, at least one of the pusher bars is in engagement with the ground, and is actuating the vehicle at all times.

Each pusher bar is composed of upper and lower members 51 and 52 and is equipped with a coiled cushioning spring 53 interposed between the members and arranged to cushion the stroke to effect an easy engagement of the same with the supporting surfaceand to prevent jar and vibration from beingv communicated to the vehicle and its occupants The coiled spring is' arranged in a slot or opening 54 in the upper member 51 which is provided at the lowerportion with an encircling cuff 55 forming a guide for the lower member 52. The lower member 52, which is in the form of a shank or bar, is provided atits upper end with a head 56 which is engaged by the lower end of the coiled spring 53, and the upper portion of the coiled s ring is arranged within a metallic; strap 5 which extends around the upper sectional member of the push bar. I

The lower terminal portion of the section 52 of the push bar extends below the pivot 50of the inclined brace or thrust bar and is adapted to receive either a shoe 58 or a shovel 59. The shoe 58, which may be constructed of metal or any other suitable material, is provided with a socketor'opening 60 to receive the lower terminal portion of the push bar, and it is secured to the same by a bolt 61 or other suitable fastening devicewhich pierces opposite side portions of the shoe. The shoe, which is provided with a solid lower end or wall 62 for engaging the ground, is designed to be usedwhen the running gear is equipped with wheels 63 and 64, but when runners are used or when the vehicle is traveling over soft ground, the

shoe 58 is removed and the shovel 59 is sub-' stituted therefor. The shovel which is secured to the push bar by the "bolt 61 prefer-.1

other-suitable device may be employed for enabling'the push bars to properly engage soft or slippery surfaces.

The pivotally mounted adjustable .sup-' port is yieldably connected with a pair of opposite gear elements 63 by links 64 provided at their rear ends with eyes to receive the said superimposed pivot 46. and having slots65 in their frontportions to receive pivots 66 carried by arms or extensions 67 of the gear elements. The gear elements 63 are mountedon suitable pivots 68 of standards 69, and their arms 67 project upwardly and are adapted tobe oscillated backwardly and forwardly to raise and lower the adjustable support and the propelling mechanism carried' by the same. The adjustable support and the push bars are yieldably maintained in position with relation to the gear elements by coiled springs 70 disposed on the front portions of the links 64* and interposed between shoulders 71 thereof and the said arm 67 and adapted to yield to permit the adjustable support and the' push bars to rise should thelatter encounter an obstruction whereby injury to the propelling mechanism will be eifectually prevented through such axle, but the shaft 73 may be mounted in any other suitable manner. The shaft 73 has fixed to it a central worm wheel 74 which meshes with a vertical worm 75 of a shaft 76 j ournaled in suitable bearings of a stand 77 and formed at its upper end with an operating device 78 which is' preferably in the form of a crank handle. The crank handle is provided witha spring actuated latch 7 9 arranged to engage suitable notchesor openings in the topof the stand and preferably in theform of a lever mounted on the crank 78 by a'suitable pivot 80'and having a grip orhandle portion arranged adjacent to the grip or handle portion of the crank 78, a coiled spring 81 being preferably interposed between the grip or handle of the crank and 1.
